In the experiments,
the following values were used for maximal program tape size and
work tape size:
,
.
The current implementation (which is not optimized for speed)
tests about 3,000 programs per second on a SUN SPARC ELC.
On average, a program
runs for not many more than 10 time steps before halting
or being halted. But there
are programs running for millions
of time steps, of course.
